Abstract
The utility model relates to a spinneret plate which comprises a spinneret plate body. Spinneret orifices are formed in the spinneret plate body, a cross-shaped ventilation passageway and a ring-shaped ventilation passageway are arranged in the spinneret plate body, the cross-shaped ventilation passageway starts from the periphery of the spinneret plate body and stretches to the middle of the spinneret plate body, and the center of the spinneret plate body is the circle center of the ring-shaped ventilation passageway. The spinneret plate is suitable for spinning, and all thread strands sprayed from the spinneret plate can be evenly cooled to meet process requirements.
Description
Technical field
The utility model relates to the fiber production technology field, refers more particularly to a kind of spinnerets.
Background technology
The structure of the spinnerets that is used for spinning that present stage generally uses comprises: the spinnerets body evenly is densely covered with spinneret orifice on the body.In the spinning production process, high-temperature fusant is extruded the spinnerets body under certain pressure, form densely covered high-temperature fusant thread through spinneret orifice, these melt thread temperature are very high, generally between 290～325 ℃, through the ring cold wind blower, need to spin in journey and very short time certain, evenly cool off and form the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree; Because the diameter of spinnerets is larger, tow is many, and cooling air is difficult to pass densely covered layer by layer peripheral tow and arrives the spinnerets middle part, and the tow that is positioned at the spinnerets middle part can not reach technological requirement because of cooling, and causes difficulty in spinning, affects product quality.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can make whole tow all cool off the spinnerets that reaches technological requirement.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of spinnerets, comprise: the spinnerets body, be provided with spinneret orifice at the spinnerets body, be provided with the cross ventilating duct and the annular air channel take the spinnerets center as the center of circle that are led to the spinnerets middle part by the spinnerets periphery on the described spinnerets body.
The beneficial effects of the utility model are: can make high-temperature fusant that spinnerets sprays in setting time and certain spinning on the journey, all cooling reaches technological requirement and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree uniformly, thereby makes spinning effect better.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, spinnerets body, 2, spinneret orifice, 3, the cross ventilating duct, 4, annular air channel.
The specific embodiment
Below by specific embodiment a kind of spinnerets of the utility model is described in further detail.
As shown in Figure 1, a kind of spinnerets, comprise: spinnerets body 1, be provided with spinneret orifice 2 at spinnerets body 1, be provided with the cross ventilating duct 3 and the annular air channel take the spinnerets center as the center of circle 4 that are led to the spinnerets middle part by the spinnerets periphery on the described spinnerets body 1.
Above-mentioned spinnerets, it is by arranging cross ventilating duct 3 and annular air channel 4 at spinnerets body 1, since in cross ventilating duct 3 and annular air channel 4 zones without spinneret orifice 2 and be interconnected, just there is not tow to stop the current of cooling air yet, cooling air can enter into the spinnerets middle part by the spinnerets periphery by the air channel, thereby the tow that is positioned at the spinnerets middle part also can be cooled off reach technological requirement, whole tow that spinnerets is sprayed all cool off and reach requirements, thereby make spinning effect better.
Claims (1)
1. spinnerets, comprise: the spinnerets body, be provided with spinneret orifice at the spinnerets body, it is characterized in that: be provided with the cross ventilating duct and the annular air channel take the spinnerets center as the center of circle that are led to the spinnerets middle part by the spinnerets periphery on the described spinnerets body.
